Us Patents

  • Coupler For An Image-Forming Apparatus

    view source
  • US Patent:
    6397029, May 28, 2002
  • Filed:
    Jan 11, 2001
  • Appl. No.:
    09/760316
  • Inventors:
    Harald Portig - Versailles KY
  • Assignee:
    Lexmark International, Inc - Lexington KY
  • International Classification:
    G03G 1500
  • US Classification:
    399167, 399116
  • Abstract:
    A coupler for transferring rotary motion from a drive gear to a photoconductive drum or ITM belt within an image forming apparatus. In one embodiment, the coupler includes a substantially cylindrical body having first and second ends having extensions extending outward for mating respectively with the drive gear and photoconductive drum. One surface of each of the extension may include a rounded drive surface. One end of the coupler may further include a wall that mounts against a dome extending outward from one of the drive gear or photoconductive drum. One of the drive gear or photoconductive drum may further include axially aligned ridges that are straddled by the coupler to allow for the coupler to axially slide and maintain contact with the photoconductive drum and drive gear even during misalignment.
  • Method And Apparatus For Reducing Lateral Motion Of A Transfer Belt Of A Laser Printer

  • US Patent:
    6567633, May 20, 2003
  • Filed:
    Sep 28, 2001
  • Appl. No.:
    09/965884
  • Inventors:
    Robert Leonard Burdick - Lancaster KY
    Mark Andrew Omelchenko - Lexington KY
    Stacy Marie Pargett - Richmond KY
    Harald Portig - Versailles KY
  • Assignee:
    Lexmark International, Inc. - Lexington KY
  • International Classification:
    G03G 1500
  • US Classification:
    399165, 474101, 474122
  • Abstract:
    An improved intermediate belt system (ITM module) is provided, which controls the lateral motion of the belt in the scan direction of an EP printer, without the use of edge reinforcements or other attachments added to the belt. The tracking system of this ITM module is passive, and maintains roll alignment/parallelism within a predetermined tolerance while also maintaining roll conicity-end flare to a predetermined maximum diametral variation over the roll to minimize the effect of external forces on the belt walk rate. The ITM module also provides angled tracking guides near the tension roll to control the lateral position of the belt; the position of these tracking guides is adjustable at time of manufacture to achieve the desired lateral belt position.

    Waste toner is detected in a container of an image forming apparatus. An auger is provided within the container. A switch is provided which is operable depending upon a torque associated with operation of the auger. A frequency of activation of the switch is detected. A “not full”, “near full” and “full” condition of the waste toner in the container is determined depending upon the frequency of activation of the switch.

  • Variable Force Biasing Mechanism And Electrical Connection

  • US Patent:
    7082275, Jul 25, 2006
  • Filed:
    Mar 19, 2004
  • Appl. No.:
    10/804691
  • Inventors:
    Harald Portig - Versailles KY, US
    Larry Steven Foster - Lexington KY, US
    Benjamin Alan Askren - Lexington KY, US
  • Assignee:
    Lexmark International, Inc. - Lexington KY
  • International Classification:
    G03G 15/00
  • US Classification:
    399110, 399117
  • Abstract:
    A biasing mechanism in an image forming apparatus exerts a variable force on a removable cartridge unit to generate a nip force between a roller in the cartridge unit and another roller. A pivot member is fixed to the apparatus housing. An arm is pivotally mounted in the housing about the pivot member, with the arm in contact with a protrusion on the cartridge unit. A force generating member is mounted in the housing and contacts the arm so as to urge the arm to pivot about the pivot member and press against the cartridge unit. The resulting force exerted on the cartridge unit by the arm varies according to the point of contact between the cartridge unit and the arm. In some embodiments, the arm and the cartridge unit protrusion are electrically conductive, and an electrical contact is established as the arm is pressed against the protrusion.
  • Coupling Retraction Mechanism For An Image Forming Device

  • US Patent:
    7130562, Oct 31, 2006
  • Filed:
    Mar 26, 2004
  • Appl. No.:
    10/810139

    Larry Steven Foster - Lexington KY, US
    Edward Lawrence Kiely - Lexington KY, US
    Robert Galon Newman - Lexington KY, US

  • Assignee:
    Lexmark International, Inc. - Lexington KY
  • International Classification:
    G03G 21/18
    G03G 15/00
  • US Classification:
    399112, 399110, 399125
  • Abstract:
    In an image forming apparatus containing a plurality of rollers disposed with generally parallel axes, a retraction plate containing a plurality of rotational couplings is movable between engaged and retracted positions. Each rotational coupling is operative to transmit a rotary force to each cartridge when the retraction plate is in the engaged position. The couplings move laterally in an axial direction of the rollers as the retraction plate moves between the engaged and retracted positions, in response to an applied force. In one embodiment, the retraction plate is rotated about a pivot point to move the couplings between engaged and retracted positions. In another embodiment, the retraction plate is translated laterally in the axial direction of the couplings.

  • International Classification:
    G03G 15/00
  • US Classification:
    399110, 399107, 399125
  • Abstract:
    A door assembly movably positioned to a body of an image forming device. The door assembly includes a first frame and a second frame. The first frame is movably attached to the body, and the second frame is movably attached to the first frame. The movable connections between the frames and the main body cause accurate locating of a photoconductive member mounted on the door assembly within the body. In one embodiment, a contour surface within the body contacts the second frame to locate the second frame within the body. Methods of moving the door assembly are also disclosed including moving the door assembly from an open orientation that is spaced from the body, to a closed orientation that is in proximity to the body. The movement of the door assembly causes interaction between the frames and the body to accurately locate the second frame.

  • Abstract:
    Embodiments for driving a removable element within an image forming device. An output member positioned within the image forming device mates with an input member of the removable element. The members include ribs that mate together such that rotational force from the output member is transferred to the input member. The ribs of the members include non-complementary contact surfaces that provide for limited contact along the contact surfaces that accurately transfers the driving force.
